Research Interests

Following a number of years work in the field
of query language interfaces to relational and logic databases (including Natural Language
Processing), my more recent research since 1995, has focussed on the area of semantic
query optimisation and rule analysis.

Specific issues addressed include formal rule
set generation, representation, analysis, selection and integrity consistency, together
with the development of non-exponential query transformation algorithms. Experimental
results show significant improvements in reducing query response opening the way to
innovative commercial use.

The research can be used in the context of
all classes of DB systems including relational and object-oriented and offers distinctive
theoretical and experimental insights into the rich and productive area of improving
information retrieval from large databases.
